November 2002 lunar eclipse
In-game article clicks load inline without leaving the challenge.
A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Wednesday, November 20, 2002, with an umbral magnitude of −0.2246. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's penumbra. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. Occurring about 3.8 days after apogee (on November 16, 2002, at 6:30 UTC), the Moon's apparent diameter was smaller.
Visibility
The eclipse was completely visible much of North and South America, Africa, and Europe, seen rising over western North America and the eastern Pacific Ocean and setting over east Africa and west, central, and south Asia.

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.

Saros 116
This eclipse is a part of Saros series 116, repeating every 18 years, 11 days, and containing 73 events. The series started with a penumbral lunar eclipse on March 11, 993 AD. It contains partial eclipses from June 16, 1155 through September 11, 1299; total eclipses from September 21, 1317 through July 11, 1786; and a second set of partial eclipses from July 22, 1804 through October 7, 1930. The series ends at member 73 as a penumbral eclipse on May 14, 2291.
The longest duration of totality was produced by member 40 at 102 minutes, 40 seconds on May 16, 1696. All eclipses in this series occur at the Moon’s ascending node of orbit.

Eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

Tritos series
This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.

Inex series
This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.
